When I load my mpg file into VCDeasy I goto chapters and get

Number Of Possible Chapter Entry Points:1

and can not add any chapters to my video.

How can I fix it? I have tried reencoding the mpg a heap of times with various setting using TMPGEnc-2.02.31.119 but I still only get 1 chapter allowed in the video file. Also tried Demuxing and Remuxing the mpg also but It still only allowed 1 chapter.

P.s. Also when I load the file into VCDEasy it says the file requires autopadding? Whats this and how you you resolve it
